(304 mm) diameter to be used for continuous service in condensate return lines for the specific maximum temperature and pressure covered by this specification, 250°F (121°C) and 125 psig (862 kPa). 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are provided for information purposes only. 1.3 The dimensionless designator NPS has been substituted in this specification for such traditional terms as "nominal diameter", "size", and "nominal size". 1.4 The following safety hazards caveat pertains only to the test method portion, Section 10, of this specification: 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Note 1-There is no similar or equivalent ISO standard.

5.1 This is not a routine test. The values recorded are applicable only to the sewer being tested and at the time of testing.1.1 This practice covers procedures for testing the joints of installed precast concrete pipe sewer lines, when using either air or water under low pressure to demonstrate the integrity of the joint and the construction procedures. This practice is used for testing precast concrete sewer lines utilizing rubber gasket sealed joints.NOTE 1: The user of this practice is advised that methods described herein may also be used as a preliminary test to enable the manufacturer or installer to demonstrate the condition of sewer pipe prior to delivery.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.NOTE 2: The owner shall specify the following: who will conduct, observe, and furnish labor, material, and measuring devices and pay for the tests; who is responsible for determining local ground conditions; and whether an air or water test is to be used.NOTE 3: The user of this practice is advised that test criteria presented in this practice are similar to those in general use. Pipe shall be accepted by infiltration or exfiltration testing utilizing Practice C969 (C969M).NOTE 4: Test times tabulated and the rate of air loss in this practice are based on successful testing of installed pipelines. However, since air and water have different physical properties, retests of some pipelines not meeting field air tests have been successful when tested with water.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautions are given in Section 6.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers the in-service inspection and electrical testing of temporary protective grounding jumper assemblies used by electrical workers in the field on de-energized electric power lines, circuits, and equipment. These assemblies consist of flexible cables, ferrules, clamps, and connectors. The test procedures detailed here provide an objective means of determining if a grounding jumper assembly meets minimum electrical specifications. The application, care, use, and maintenance of this equipment are not addressed in this specification.1.1 This specification covers the in-service inspection and electrical testing of temporary protective grounding jumper assemblies which have been used by electrical workers in the field.1.2 This specification discusses methods for testing grounding jumper assemblies, which consist of the flexible cables, ferrules, clamps and connectors used in the temporary protective grounding of de-energized circuits.1.3 Manufacturing specifications for these grounding jumper assemblies are in Specifications F855.1.4 The application, care, use, and maintenance of this equipment are beyond the scope of this specification.1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.6 The following safety hazards caveat pertains only to the test portions of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This is not a routine test. The values recorded are applicable only to the sewer being tested and at the time of testing.1.1 This practice covers procedures for testing concrete pipe sewer lines, when using the low-pressure air test method to demonstrate the integrity of the installed material and the construction procedures. This practice is used for testing 4 to 24-in. circular concrete pipe sewer lines utilizing gasketed joints.1.2 This practice is also used as a preliminary test to enable the installer to demonstrate the condition of the line prior to backfill.1.3 A complete metric companion to Practice C 924 has been developed—C 924M; therefore, no metric equivalents are presented in this practice.Note 1—The user of this practice is advised that air test criteria presented in this practice are similar to those in general use. The test and criteria have been used widely and successfully in testing smaller diameter pipe, but additional data are required to confirm the safety and applicability or develop criteria for pipe larger than 24 in. in diameter. Larger pipe will be accepted more conveniently by visual inspection and individual joint testing.Note 2—The user of this practice is advised that no correlation has been found between air loss and water leakage.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use (see Section 6, Safety Precautions).
